1. An anchoring system, comprising:
a suture anchor configured for insertion into a bore formed in a bone, the suture anchor including:
an anchor body including a threaded outer surface, an etch line, a bore extending from a proximal end of the anchor body to a distal end of the anchor body, and a stop surface located within the bore and spaced proximally from the distal end of the anchor body; and
a distal member that is rotatable relative to the anchor body about a longitudinal suture anchor axis, the distal member having an aperture that traverses the distal member, the aperture including an eyelet and a slot, the eyelet and the slot being sized to permit a suture to traverse the distal member, wherein a length of the slot is greater than a length of the anchor body from the proximal end of the anchor body to a proximal end of the etch line to prevent over tensioning of the suture during implantation of the suture anchor, wherein the distal member includes a projection extending from a proximal end thereof, the projection including a lip, a shoulder spaced distally from the lip, and a lumen configured for receipt of a delivery device, wherein upon assembly of the anchor body to the distal member, the lip engages the stop surface within the bore and the shoulder engages the distal end of the anchor body, and wherein the distal member includes an outer surface including a plurality of fixation projections configured to provide an outward force sufficient to prevent the suture anchor from backing out of the bore after insertion.
